The only habit from running cross country in high school that I've carried with me through life is drinking water. I probably go through a gallon of water a day by constantly filling up a water bottle similar to this free PUR water bottle. In fact, I've probably got like 9000 of these things in my kitchen cabinets, but of course I just signed up for this as well. 🙂
